National Semiconductor Corp. (www.national.com) has unveiled the LP3950, reportedly the first color LED driver with audio synchronizer. With this feature, the color LEDs on the phone or MP3 player blink and change color in time with the music or ring tones. Offered in a 32-pin thin CSP package, the LP3950 also comes with two RGB LED outputs that can drive up to 300 mA for color LEDs or for camera flash LED. National Semiconductor has also introduced the LP3942 and LP3931 chips for handheld devices. Applications include cell phones, smart phones, global positioning systems, and personal digital assistants.
